BEIJING, Feb. 4 (Yonhap) -- South Korea's chief nuclear envoy met with his Chinese counterpart on Monday and urged Beijing to exert its influence on Pyongyang to abandon its planned test of a nuclear device, a Seoul official said.

Lim Sung-nam, Seoul's chief envoy to the six-party talks aimed at ending North Korea's nuclear weapons program, held talks with his Chinese counterpart Wu Dawei as tensions rise on the Korean Peninsula over the North's threats of a nuclear test.

During the meeting, Lim and Wu expressed concerns over the North's planned nuclear test and shared common views that a nuclear test by Pyongyang will pose a grave threat to peace and stability on the Korean Peninsula, said the official with the knowledge of the talks.

North Korea has vowed to conduct its third nuclear test in response to the U.N. Security Council resolution tightening sanctions against it as punishment for its December rocket launch. The country had previously detonated nuclear devices in 2006 and 2009.

Officials in Seoul have said North Korea has completed all preparations and can detonate a nuclear device at any time.

On Sunday, North Korea's young leader Kim Jong-un convened a meeting of high-level military officials and issued "important" guidelines to them, in the latest indication that Pyongyang might soon carry out a nuclear test.

China, which endorsed the latest U.N. Security Council resolution against North Korea, has apparently warned the North against conducting a nuclear test.

China's state-run newspaper run by the ruling Community Party, The Global Times, recently ran an editorial that indicated Beijing would cut aid to Pyongyang if it goes ahead with a nuclear test.
